Discoloured icons in Plasma 5.27


I’ve been configuring a fresh install of Manjaro (KDE Plasma version, obviously) and have noticed something strange: A lot of the app icons seem to be grey, even though they should be white. At first I thought this may be some issue with the icon pack itself, but the icon files themselves seem to be in order. To make things even weirder, the affected icons only appear grey in the task manager and the application launcher. On the desktop, in the application editor, as well as in the files themselves, the icons appear white.

I tried reinstalling the icon pack in question (Simply Circles by ju1464) and playing with the color scheme, but had no luck so far. Any ideas on what might be the cause of this issue are greatly appreciated. Thanks!
